A plutonium atom is made up of positively-charged protons and neutrally-charged neutrons found in the central region of the atom called the nucleus. Negatively-charged electrons can be found outside the nucleus
Arrange the following statements in a sequence which involves the calculation of the atomic number and mass number for an atom of an element with 15 electrons and 16 neutrons. (a) A=Number of protons + Number of neutrons A=Z+ Number fo neutrons A=15+16=31 (b) Number of protrons...
In the WNR Facility at the Los Alamos National Laboratory in the United States, this white beam is produced by directing the 800-MeV protons on a tungsten target. When the protons hit the tungsten target, they shatter the tungsten nucleon (much like when a glass shatters into many pieces) ...
Give the symbol for an element with 79 protons, 117 neutrons, and 79 electrons. Give the symbol for an element with 5 protons, 6 neutrons, and 5 electrons. How many neutrons and protons (nucleons) does an atom with the symbol S have? a. 33 b....
Number of neutrons= 16 Explanation of Solution Given,1531X Atomic number,Z =15 Mass number,A =31 The atomic number of the element is equal to the number of protons. The mass number is equal to the sum of the number of protons and neutrons. ...
so it lies on the right-hand side of the modern periodic table. The neon element symbol is Ne. It has the atomic number 10. So, in the neon atom, the number of protons and electrons is 10 each. Themass numberof neon is 20 amu. So, the number of neutrons in the neon atom is 10...
the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope...
Main articles: Isotope and Stable isotope Isotopes are atoms of the same element (that is, with the same number of protons in their atomic nucleus), but having different numbers of neutrons. Most (66 of 94) naturally occurring elements have more than one stable isotope. Thus, for example, ...
How many electrons contain the ion that has 13 protons 10 electrons and 15 neutrons? Which monatomic ion has a charge of +1 and the electron configuration [Kr]4d^105s^2? Write the element symbol and charge. How many unpaired electrons are ...
View Solution The number of neutrons are equal to the number of protons present in the nucleus of two elements and their respective dinegative ions possess 8 electrons in L and M shells respectively . Then the ratio of mass numbers of the two elements is ...
